WILLIAM J. MEINEL, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO EDWARD G.

BUDD MANUFACTURING COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A COR- PoRATIoN or PENNSYLVANIA.

READING MACHINE.

Application filed July 31, 1920. Serial No. 400,382.

To all whom it may concern:

Be it known that I, WILLIAM J. MEINEL, residing at Philadelphia, Pennsylvania, have invented certain new and useful Improvements in Beading Machines, of whichv Ideclare the following to be a full, clear, and exact description. v

My invention relates to improvements in beading machines, and, more particularly, to improved means for driving and controlling such machines.

One of the chief objects of my invention is to provide a beading machine which is motor-driven, and in which the motor drive is so arranged that the beading machine will be fully as simple and accessible as a hand driven machine. Another object of my invention is to provide a motor driven beading machine, which is simple and accessible, and which may be very readily controlled by the workman, so that the drive 'canbe quickly stopped at the end of the beading operation.

Further objects, and objects relating to economies of material and details of construction, will definitely appear from the detailed description-to follow. I accomplish the objects of my invention by the devices and means set forth in the following specification. and pointed out in the appended claims.

A structure constituting a preferred embodiment of my invention is illustrated in the accompanying drawing, forming a part of this specification in which:

Figure 1 is a view in side elevation of a machine embodying my invention, the drive pulley and brake lever being shown in vertical section; and

Fig. 2 is a view in end elevation of the machine.

In the drawing-similar reference'numerals refer to similar parts throughout the several views.

My invention is clearly defined.

that the work on which it operates may be readily shifted with reference to the machine, so that the work may be fed into the machine from a variety of angles and so that the work may be readily shifted to and fro around the base of the machine.

I have provided a motor driven beading machine which. meets this requirement, and which is designed to take the place of the hand driven machines heretofore used.

The motor drive is so arranged that it does not interfere with the feeding of the work to the machine, and the control is such that the machine may be readily controlled by the workman while he is feeding the work in the machine.

I have shown a beading machine comprising standard 10 having a socket 11 at the upper end thereof. An arm 12 is provided with a cylindrical post 13 which fits in the socket 11 and is held against rotation therein by the set screw 14:. The bolt 15 extends 1 Near the gear 19 there are formed a pair of seats 20 on the arm 12, and the upper arm 21 is provided with a pair of seats 46 which rest on the seats 20, the two arms being secured together by bolts passing through said parts. A longitudinally extending shaft 22 is'mounted in the arm 21 and carries at its outer end a bead roll 23 cooperating with the roll 17, these two rolls being complementarily formed with reference to each other to produce the required bead. A tie strap 45 connects the arms 21 and 12. On the inner end of the shaft 22 there is mounted a gear 25, which meshes with the gear 19 above referred to. JThe gears 19 and 25 have the same number of teeth, so that the shafts 16 and 22 are driven at the same speed in opposite directions.

A stub shaft 35 is mounted in the arm 21 and carries a pinion 36 which meshes with the gear 18. The stub shaft 35 also carries a gear 24 meshing with a pinion 31 which will be described later. In the upper part or the arm 21 there are provided a pair of seats 26 and 27, on which is mounted a motor 28 fastened to said seats by suitable bolts. The motor shaft 29 carries a pulley 30. c On the extreme inner end of shaft 16 there is loosely mounted a pinion 31 which rotates freely on said shaft. To the extended hub 32 of this pinion there is keyed the pulley 33. A belt 37 passes over the pulley 30 and the drive pulley 33, so that the latter is driven "from the motor.

A hell-crank lever is journaled on the stub shaft 35, and the said bell-crank lever has one arm 38 which is connected by the rod with a treadle (not shown). The other arm 40 of the bell-crank lever carries an idler pulley 41 at the free end of the arm 40 and a laterally projecting pin 42 which is mounted in a slot 14 of the brake shoe 43. A spring 45 is fastened at one end to the base of the motor and at the other end to the arm 38 of the bell-crank lever, and tends to throw the bell-crank lever to a position in into tensioning engagement with the belt 37, so as to tension'the belt. The motor drives the pulley 30 and through the belt 37 the pulley '33. This pulley drives the pinion 31, which meshes with the gear 24, and the latter gear drives the pinion 36, which meshes with the gear 18 on the shaft lfi. As has been explained before, this causes both .the

shafts 16 and 22 to revolve at equal speeds in opposite directions. When the beading operation'is completed, the operator removes his foot from the treadle and the spring 45 throws the bell-crank lever to a position in which the tension on the belt is released and the brake shoe is held on the surface of the usages pulley 33. This stops the machine almost at once, so that the work may be removed.

It will be noted that the arm 12 and the whole working head can be swung around by-loosening the set screw 14 so as to allow the post 13 to turn in the socket 11. Thispermits the swinging of the beading machine to the most favorable'position. The motor and driving connections are all carried by the head, so as to swing with it. The

- motor is positioned substantially in line with the post 13, so that the weight of the motor does not tend to unbalance the machine.

I am aware that the particular embodihere is susceptible of considerable variation without departing from the spirit of my invention, and, therefore, I claim my invention broadly, as well as specifically, as indicated by the appended claims.

Having thus described my invention, what l claim as new and desire to secure by Letters Patent is 1. In a machine of the class described, a standard, a head mounted thereon and rotatably adjustable around a vertical axis, a pair of shafts journaled in said head and each carrying a beading roll, driving mechanism for said shafts including a motor disposed in balanced relation with respect to said axis, a pulley fixed on one of said shafts, a belt connecting said motor and pulley, brake means, and belt-tensioning means, all of said driving mechanism being carried by and rotatably adjustable with said head.

2. In a power driven beading machine, a standard, a head carried thereby, beading mechanism carried by. said head and including a heading roll shaft, a pulley journ'aled on said shaft, reduction gearing between said shaft and ulley, an electric motor carried by said liead, a driving belt connecting said power driving motor and pulley, a bell-crank lever pivoted on said head, a brake-shoe carried by said lever and acting on the pulley, and an idler roll carried by the leverand acting on said-belt to tension the same.

In testimony whereof, I affix my signature.
